"For superior audio effects in games and such, SonicFury uses Sensaura's 3D audio implementations, and they claim many kick ass effects audio effects that seemingly go above and beyond EAX and A3D's HRTFs (Head Related Transfer Function) algorithms, the two most widely used 3D sound APIs. For example, MacroFX focuses on "near-field proximity effects" which means simulating sounds very close to the listener such as buzzing near his ear or the whooshing of bullets going right by your head, which is something that current HRTF methods such as EAX are not able to pull off. Also implemented is MultiDrive technology which theoretically is able to create a true 360° horizontal and vertical "sound field" for never before realized surround sound with just using 4 speakers.”
